Analysis of heating and cooling load requirements, considering building construction type, geometry, infiltration, occupancy effects, and daily load variations. Heating design addresses water heating systems, electrical heating, central heating, heating of low and high-rise buildings, selection of heaters, boilers, pumps, piping design. Cooling design addresses refrigerants, refrigeration cycle, evaporator, compressor, condenser, thermostatic expansion valves, refrigeration system control equipment, motor and motor control equipment, refrigeration accessories, calculation of refrigeration piping and absorption systems. Computer applications for heating and cooling load analysis will be introduced to develop energy saving solutions. Analytical techniques and building codes are discussed through case studies and design projects.
